"Great barrel. Sturdy, VERY easy to install to both of my upper receivers, and durable. Somewhat extendable once the retention set screws are loosened for a bit of extra length which is awesome; wasn't enough for the 19" barrel I have but still great. My one issue is its stability; the sheer length just doesn't let it free float too easily unless I messed something up. Simple fix: A piece of 1.5" pipe insulation jammed into the end of my rail system; stabilizes it perfectly and is a dark gray you have to look for it on the gun and thus maintains the tacticool look rather than looking like something jury rigged straight into the Fallout universe.

"Solid and straight barrel. The gas block cutouts are too shallow to mount a G&P, G&G, and JG gas block/front sight. A dremel fixes this. It mounted perfectly on my G&P MOTS receiver with a standard delta ring.

"i suppose the quality is nice but the paint finish on the threads is much too thick. Will have to do some modification to thin the pain or completely sheer it off. Also, my barrel came loose so make sure u have a SMALL allen key.
